WinRAR is a trialware file archiver and compressor utility for Windows. It can create archives in RAR or ZIP file formats,〔Manuel Masiero (18 March 2013)("Compression Performance: 7-Zip, MagicRAR, WinRAR, WinZip" ) ''Tom's Hardware''. Retrieved 27 November 2013.〕 and unpack numerous archive file formats. There is an Android app called "RAR for Android",〔(RAR for Android; RARsoft. )〕 and command-line versions called "RAR" and "UNRAR" (widely released since autumn of 1993), available for Mac OS X, Linux, FreeBSD, Windows console mode, and MS-DOS. ==Overview== WinRAR and the RAR file format evolved over time. Support for the archive format RAR5, using the same RAR file extension as earlier versions, was added in v5;〔Martin Brinkmann (29 April 2013)("WinRAR 5.0 introduces the new RAR 5 format. What you need to know" ) ''Ghacks''. Retrieved 27 November 2013.〕 files in the older RAR file format are now referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives.〔 The RAR5 file format added some features, but removed comments for each file (though archive comment still remains), authenticity verification, and specialized compression algorithms for text and multimedia files. RAR5 also changed the file name for split volumes from "archivename.rNN" to "archivename.partNN.rar".〔 The RAR5 file format increased the maximum dictionary size to 1 GiB; 11 different compression directory sizes from 1 MiB to 1 GiB are available, with the default in version 5 increased from 4 MiB to 32 MiB, typically improving compression ratio. AES encryption, when used, was increased from 128- to 256-bit. Maximum path length for files in RAR and ZIP archives is increased to 2048 characters.〔 Options added in v5 include 256-bit BLAKE2 file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, Quick Open record to allow large archives to be opened faster.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WinRAR」の詳細全文を読む スポンサード リンク
